Improvement in locomotives



UNITED STATES PATENT OFFICE.

To BERNHARD scHAEFER AND YORK, N. Y.

CHRISTIAN BUDENBERG, OF NEW IMPROVEMENT IN LOCOMOTIVES.

Specification forming part of Letters Patent No. 411,0 55, dated August30, 1864.

To all. w/wm may concern.-

Be it known that I, GEORGE THOMAS, ot' Frankfortonthe-Main, free city ofFrankforton-the-Main, have invented a new and useful Improvement in theApplication of Locomotives as Steam Fire-Engines, and I do herebydeclare that the following' is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference bein g had to the accompanying drawings, forming' partof this specitica tion, in which- Figure l represents a side elevationot' a locomotive constructed according to my in velition. Fig. 2 is afront elevation of the same. Fig. 3 is a detached side elevation of theshoe which I use to elevate the driving-wheels from the ground. Fig. 4is a frontelevation of the same. l

Similar letters of reference indicate like parts. i Arepresents alocomotive constructed in,

the ordinary manner, and supported bythe usual number of wheels B B.These wheels have their bearings on suitable axles, and the wheels B,which form the drivers connect with the steam-pistons in any ot' thewell-known methods, either under the boiler C, as shown in the drawings,or in any other suitable manner.

D D* are the feed-pipes, which lead from the boiler to the tender, andthe water drawn from the tender is forced into said boiler, either bythe action of the force-pumps E or by injectors Wfhen force-pumps areused, a three-way cock is placed between the check-valve b and theboiler, and a nipple, c, projecting from one side of the shell ot thethree-way cock, connects by a hose-pipe, d, with the air-chamber F,which is put upon a separate platform, either stationary or movable, orwhich may be connected to some portion of the locomotive. Another hose,e, with a suitable nozzle, throws or carries the water to the desiredspot.

The connection between the tender and force-pumps is closed bystop-cocks f, andthe connection between the hose g and feed-pipes isopened by a cock, gf. This hose extends to a well or reservoir, andforms the suction-pipe. The water elevated through this pipe or hose isdriven by the action of the force-pumps into the air-chamber F, and ajet ot Water ot' considerable power can be obtained.

In order to operate the pumps without propeiling the locomotive, thedriving-wheels B have to be blocked up, and this purpose I et'- fect bymeans ot' the shoe G, detached views of which are shown in Figs. 3 and4. If de sired, this shoe may be furnished with wheels h and a handle,t', so that it canbe used as a hand-car for the transportation of theairchamber F, or of other articles from one place ofthe road to theother. A drum, j, mounted on the axle of the wheels h, serves to Wind upthe hose in carrying` the same from one place to another.

It instead of the pumps E the injector E* is used, the air chamber canbe dispensed with. The suction-pipe is connected to the pipe Dt, and thecommunication between the boiler and injector is closed by a threewaycock, at, which, in closing said communication, opens that between theinjector and hose 0*. By the action of the steam admitted from theboiler to the injector a current of Water will be forced through thehose et, and by the application of a suitable nozzle a jet of considerable power will be produced.

What I claim as new, and desire to secure by Letters Patent, is-

The application to a locomotive of hosepipes d e* g, with or without anadditional airchamber, F, and with suitable stop-valves, a a* gf, iu themanner and for the purpose substan tially as herein shown and described.

G'. THOMAS.
